Veteran rocker Jerry Lee Lewis has wed for the seventh time.The 76-year-old Great Balls Of Fire singer exchanged vows with his caregiver Judith Brown in Natchez, Mississippi on 9 March (12). According to People magazine, the rocker's wedding plans were so secretive even his live-in daughter Phoebe was unaware her dad was about to exchange vows again. Brown, who is 14 years younger than Lewis, was previously married to the star's cousin Rusty. Lewis first wed in the early 1950s when he made Dorothy Barton his wife and he caused an uproar in 1957 after tying the knot with then-13-year-old Myra Gale Brown - his first cousin once removed. They split after 13 years together. The rocker split from his sixth wife Kerrie MCCarver in 2004 after 20 years of marriage.
